# List of megaprojects

This is a list of megaprojects, which may be defined in the following categories:
* Projects that cost more than US$1 billion and attract a large amount of public attention because of substantial impacts on communities, the natural and built environment, and budgets.
* Projects with "initiatives that are physical, very expensive, and public".
Some examples include bridges, tunnels, highways, railways, hospitals, airports, seaports, power plants, dams, wastewater projects, Special Economic Zones (SEZ), oil and natural gas extraction projects, public buildings, information technology systems, aerospace projects, and weapons systems. This list identifies a wide variety of examples of major historic and contemporary projects that meet one or both megaproject criteria identified above.

## Disaster cleanup

While most megaprojects are planned and undertaken with careful forethought, some are undertaken out of necessity after a natural disaster occurs. There have also been a few human-made disasters. Major restoration was necessary after the destruction caused by World War I and II, some of which was paid for by German reparations for World War I and for World War II.

## Sports and culture projects

Every Olympic Games and FIFA World Cup in the latter part of the twentieth century and entering into the 21st century has cost more than $1 billion in arenas, hotels etc., usually several billions. The Olympic Games are considered to be the world's foremost international sporting event with over 200 nations participating. Sports-related costs for the Summer Games since 1960 is on average $5.2 billion (USD) and for the Winter Games $393.1 million dollars. The highest recorded total cost was the 2014 Sochi Winter Olympics, costing approximately US$55 billion. The International Olympic Committee requires a minimum of 40,000 hotel rooms available for visiting spectators and an Olympic Village that is able to house 15,000 athletes, referees, and officials.
